COVERING FOR PIPES, 84C.

SPECIFICATIQN forming part `of Letters Patent No. 3%7,63L, dated August 17, 1886.

Application filed February 2G, 1886. Serial No.193,280. (Model.)

I do hereby declare that the following is a l covering.

full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to thejaccompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. p

My invention relates to improvements in `non-conduetor-of-heat coverings for pipes, e.,

the objects of which are facility and convenience of application and removal and simplicity and cheapness of construction.

In the accompanying drawings like letters designate the same parts in the several figures.

Figure l is a cross-section of my improved Fig. 2 is a perspective View of the interiorofone section of the same. Fig. 3 is a longitudinal section of a portion of two sections of the covering, showing the method of joining the same; and Fig. 4 is a perspective View of a portion of the exterior casing and of the lining and the device for holding the latter for illing with the non-conductor of heat.

My improved covering is designed particularly for use with pipes and like bodies, and is made in sections A A of convenientlength, each composed of a sheet-metal casing, B, a lining, C, of wrenetting or other suitable material secured thereto at a, folded together and adapted at the middle of the section to the exterior of the 'pipe N or body to be covered, and of a filling of mineral wool or other suitable non-conductor of heat introduced between said casing B and lining C in two or more segmental sections, as shown in Figs. l and 2.` The ends and outer edges of the 1ining C are fastened to casing B by wires an, or other suitable means, and the :lling thus se curely held in place whether the covering is applied to the pipes or not. y

The edges of casing B are folded in opposite directions, one outwardly and one inwardly,

so as to'forxn an interlocking joint at b, as shown in Fig. l, by means of which the sections are readily and securely clasped about the pipes N or body to be covered, and may be easily unclaspcd and removed when desired. The casing B is preferably extended at one end of the section beyond the filling and lining C, so as to overlap the adjoining Section, at the adjacent end of which the filling and lining are made flush, or nearly so,with the casing B, as seen in 3.

For the purpose of inserting the mineral Wool or other lling between the casing B and lining O, I clamp the latter nextto its fastening to said casing at a between the thin steel plates B l?, provided for that purpose, and made of a width equal to the desired thickness of filling,and fold the sections of said lining C in opposite directions over Lthe upper edges of said plates l? l?, as shown in Fig. 4. After the filling has been inserted and secured in place the plates P l? are withdrawn. In this manner the covering is formed in two or more segmental sections connected, as at a, by the exterior casing, B, so as to be easily spread and placed about or removed from the pipeN or body to be covered, and when secured in position to form a continuous cylindrical ineasement.

I claim- Y l. Av covering for pipes, Soc., composed of an outer metallic casing, B, lining C, a non conductor-of-heat lling inclosed and held by said casing andv lining in connected segmental sections, and wires a n, securing the outer edges and ends of said lining to said casing B and retaining thefilling in place, substantially -as and for the purposes `set forth.

2. A covering for pipes, &c., composed of an outer sheet-metal casing, B, the edges of which are turned in opposite directions to form a locking-joint, lining C, and a non-couductor-of-heat filling inclosed and held by said casing and lining in connected segmental Sections, substantially as and for the purposes set forth.

3. A covering for pipes, &c., formed in sections A A, each of which 1s composed of an i Si 3471531 Y outer sheet-metal easing, B, zi lining, C, and a In testimony that lI claim the foregoing as non-conductor-ofhent illingr ielosed and held my own lailix my signature in presence oftwo in connected segmental sections by said lining Witnesses. C and outer easing, ll, which is extended at TRUMAN MERRIAM. 5 one end beyond smid llling to overlap the ad- XVitnesses:
